OLIVER BARRATT, OF NElV YORK, N. Y.

, FLOOR-DRAINAG E VALVE.

SPECIFICATION forming part of Letters Patent No. 565,320, dated August4, 1896.

Application filed April 25 1896.

To all whom it may concern.-

Be it known that I, OLIVER BARRATT, of New York city,in the county andState of New York, have invented a new and Improved Floor-DrainageValve, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improvedfloor-drainage valve, more especially designed for use in tiled floorsof hospitals and other buildings to carry off the floor wash-water, thevalve being arranged to insure a proper closing after being used by theattendant, to prevent sewer-gas from entering the room in which thevalve is located.

The valve consists principally of a bowlshaped valve-body provided inits bottom with a valve-seat, a yoke extending in the said body andcarrying a cap, and a valve adapted to be seated on the said valve-seatand having its flange screwing into the said cap for opening and closingthe valve.

The invention also consists of certain parts and details andcombinations of the same, as will be fully described hereinafter, andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both the figures.

Figure 1 is a sectional side elevation of the improvement on the line 11 of Fig. 2, and Fig. 2 is a plan View of the same with parts brokenout.

The improved drainage-valve is provided with a bowl-shaped body A,adapted to be set in the floor B in such a manner that the top flange Aof the valve-body is flush on its upper surface with the surface of thefloor B, as is plainly indicated in Fig. 1. The lower end of thevalve-bodyA is provided with the threaded offset A to be connected witha pipe leading to a sewer or other suitable place of discharge. In thebottom of the valvebody is also formed a valve-seat A leading into theoffset A and adapted to be closed by a valve 0, held on a valve-stem D,screwing in a cap E, secured on the top of a yoke F integral with thebody A, the said yoke having a series of posts rising vertically fromthe bowl, so as not to restrict the flow ofthe water passing into thebowl and through the Serial No. 589,077. (No model.)

open valve 0 and the valve-seat into the offset A The upper end D of thevalve-stem D is made polygonal, to be engaged by a correspondingly-shaped tool for conveniently turning the valve-stein to screw thesame up or down and open or close the valve 0. Now when the valve 0 isin a closed position, as illustrated in Fig. 1, then the top surface ofthe polygonal end D is flush with the under side of a cover G for thebody A, the said cover being hinged at G to the body, and the cover isadapted to be seated on an annular shoulder A formed in the body, as isplainly shown in the drawings. When the cover G is in this position, itstop surface is flush with the floor and the flange A, as is plainlyshown in Fig. 1.

The device is used as follows: When it is desired to run wash-water orother liquids from the floor to the sewer, then the attendant swings thecover G into an open position, so'as to give access to the interior ofthe bowlshapcd body A. The operator now turns the valve-stem D to raisethe valve 0 off of the valve-seat A and now the attendant can sweep thewash-water or other liquid into the body A, so that the water will runthrough the open valve-seat A into the oifset A and the pipe connectedwith the] sewer or other place of discharge. Now when the water has runoff and the operator neglects to close the valve 0, but swings the coverG downward, the said cover will not close or seat itself on the shoulderA owing to the valve-stern D projecting above the top surface of theflange A, as indicated in dotted lines in Fig. 1, and consequently theattendant or other person will at once notice that the valve is not inthe proper position, and the attendant will be required to screw thestem D downward and 7 seat the valve 0 before the cover G will find itsseat on the shoulder A Under the arrangement described the valve 0 mustbe in a closed position when the cover G is seated on the shoulder A, toprevent sewer-gas from passing out into the room in which the valve islocated.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent---- 1. A floor-drainage valve, comprising abowl-shaped valve-body provided in its bottom with a valve-seat, a yokeextending in the said body and carrying a cap, and a valve adapted to beseated on the said valve-seat and having its stem screwing in the saidcap, substantially as shown and described.

2. A floor-drainage valve, comprising a bowl-shaped valve-body providedin its bottom with a valve-seat, a cover hinged on the said valve-bodyand adapted to be seated in the upper end thereof, to firmly hold thetop surface of the cover flush with the top edge of the valve-body,avalve adapted to be seated on the said seat, and a valve-stem carryingthe said valve and adapted to be raised and lowered, the upper end ofthe said valvestem being flush with the under side of the said coverwhen the valve and cover are in a closed position, substantially asshown and described.
